Application filed February 19, 1909. Serial No. 478,887.

To all-whom it may concern:

.ing to be a full, clear, and exact description of the invention, suchas will enable others skilled in theart to which it appertains to makeand use the same.

-My invention relates to an improvement in car truck side'frames andjournal boxes for same, the, object being to provide a con-- structionwhereby the weight and stresses are borne by the side frames, the boxesserving merely as coverings and holders for the lubricant and the dustguard.

A further objectisto so construct the side frame and its boxes, that theparts whichhold the axles in-position, are integral with: I the sideframe, thus taking all the strains" from the boxes.

-With these and other objects in view my invention consists in the partsand-combi.

nation of parts and in the details ofconstruction as will be more fullyexplained and pointed out in the claims.

In the accompanying drawings, Figurefl is a view inside elevation of thetruck, the box at one end of the frame being removed and the end of theframe shown in section. Fig.3 is a view in section onthe lines y-' 1anda-Qe of Fig.3. 1 Fig.3is aview in section lengthwise the" bearing.Fig: 4 is a view perspective of the box detached. Fig. 5 is a view insection through the side frame looking toward the bearing, the boxremoved; Fig. .6' is a plan view of same. Figs.- 7 and 8, 9 and '10,,and 11 and 12 are views in section of modifications and Figs. 13, 14 and15 are views of parts of the construction shown in Figs. 11' and 12.

l-represents the integrally east side frame I consisting of an uppermember, alower member and two cross members, the latter constituting thecolumns for the bolster 3,

the ends of which rest in the openings between the columns and aresupported-1n the well known manner. Each end of the said side frame isprovided with a ournal bearing frame, comprising a top 4,-sides 5 and acurved bottom 6, all cast'integral with the side 1 of the truck frame.The top 4 of the frame is as shown in, Fig. 6, the full width and lengthof the journalbox, and-forms .the top of the latter, while the curvedbot- Be it known that I, CHARLES B. Goon-f "SPEED, of Columbus, in thecounty of Franktom 6 of the frame is a semi-circular con tinu'ation ofthe sides 5 at. the front of the parts are cast integral, and the sides5 are provided on their lnner surfaces with the usual lugs? for'carryingthe wedges 8 and brasses 9, against which the axle 10 has directbearing.

comprises a dish-shaped bottom 12 and sides. I

3, the latter being cuff-away at their upper rear ends, toconform.to'-"'and register with the side 5 of the bearing frame as shownindotted lines in Fig. 3, so thatwhen the parts, i

are assembled, the sides '5 ofthe frame, conform to and register with.the sides of the body-1 1 of the box or housing thus forming a completeclosure. Therear end 1 lof the box is grooved. as at 15 for thereception of a dust guard, andthe open front end of the box is closed bya cover 16 hinged to the lug 17- integral with the top-4 of the bearingframe. The top 4 is also provided on" its under side .with the integrallug .18 which formsan" abutment for the wedge 8 and brass 9.

The box 11 being dish-shaped andclosed at its bottom, sides and part wayits ends, form the container'of the lubricant, and is so shapedexternally as to fit within and conform to the bottom 6 of the bearingframe as shown in Figs. 2 and 3. This box or housing is introduced fromthe outer end or boltspassing through the sides 13 ofthe box and intothe top 4 of the bearing frame, the edges 19 and 20 of the box, formedby cutting away the upper rear ends of the latter, registering with, thefront and lower edgeof the sides 5 of the frame.

WVith this construction it will be seen that the bearing frame, which asbefore explained is cast integral with the sides 1 of the truck. takesall weight, While the box 11 simply forms a closure and lubricantreceptacle, In the-construction above described the of the bearing frameand is secured by rivets- Side frame of the truck is cast integral withthe sides of the bearing frames.

In the construction shown in Figs; 7 and 8, the side frame 1 ofthetruck, 'is'formed integral with the top 4* of the bearing or boxcarrying frame, andthe boX 11 mstead of fittingv Within the frame, issecured to the bearing I greatly simplify and cheapen the cost ofcasting, and provide a construction outer side thereof. In thisconstruction the box extends back its full depth, the entire length ofthe bearing as shown in Fig. 8 and is not cut away at its ends as in theprevious construction.'

In Figs. 9 and 1 0 the box 11 is substantially identical with that shownin Figs. 7 and S, but it fits within the bearing frame as in theconstruction first described, the sides of the frame being grooved asshown in Fig. 9 for the passage of the sides of the box. In this latterconstruction the box must be no plied from the inner side of the sideframe of the truck and is secured by bolts or rivets as in the previousconstruction.

In the construction shown in Figs. 11' to 14 inclusive the box is madeof two sections, the outer section 11 of which is provided with a flange11 adapted to bear against the outer -face. of the bearing frame. Thelower half of this box is continuous from end to end forming an oilreceptacle and passes through the bearing frame, and is underlappedatits rear or inner end by the section ll which is provided with a flangell designed to abut against the rear face of the bearing frame, the twosections 11 and li forming when secured to the frame by bolts or rivetsas shown, a 'complete box and closure for the bearing.

With these constructions, it will be seen that all the stresses areborne by side frames of the trucks, and not on the box, the latterserving simply as a closure for the bearing and as a receptacle for thelubricant.

By making the box separate from the which parts most subject to strainare cast integral and in which the box which is the l part most likelyto be injured or destroyed, can be readily replaced.

It is evident that many slight changes; might be resorted to in therelative arrangement of parts shown and described without departing fromthe spirit and scope of my'in.- vention hence I would have itunderstood-j that I do not wish to confine myself to thel exactconstruction and arrangement of parts shown and described, but,

Having fully described my invention what I claim as new and desire tosecure by Letters-Patont, is j 1. A car truck side frame comprising anupper member and lower member and two cross members, a frame surroundingthe journal, a journal box top, :1 lug for attaching ournal box lid andlugs for holding ournal 'wedge and bearing, all cast integral, incombmation with a detachable journal box and. means forattaclung same toirame.

2. Atruck side frame,-a frame surrounding the journal against whichthe'journal wedge bears, withlugs forholding journal wedge and bearing,all east integral, in combination with a detachable journal box andmeans for attachingsame to frame.

3. A trurl-I side frame, a frame surrounding.

the journal for carrying journal box, a journal box top against whichournal wedge boars,

provided with hip, for attaching journal box.-

lid and with lugs for holding journal wedge and bearing, all castintegral, inCombination with a detachable journal box and means forattaching same to frame.

4. A truck side frame, a frame surrounding thc'journal and provided withlugs for holdintegratin combinatimi with a detachable journal box andmeans for attaching same to frame. i

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses. Y
